Choose your car for a more accurate estimate

Hello - I believe the humming noise you mention in the right front wheel area is a worn front wheel bearing/hub assembly. If the noise is louder when turning left while in motion, that would confirm the diagnosis. I would recommend having the right, front wheel bearing replaced by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs. The clicking noise while turning the steering wheel may be a problem with the upper steering shaft in the steering column. Cadillac has issued a technical service bulletin for problems with the steering performance (# 232985). Check with your Cadillac dealer service center for more information on this repair.
